579a794d14 cql3: de-virtualize cql3_type 
cql3_type is a wrapper around data_type, so there's no need for a class
hierarchy -- anything that depends on the actual type can be forwarded
to abstract_type_impl.

We can now use this as a value type (dropping shared_ptr<cql3_type>), but
that is left for later.

7921ef406a db: serialize via bytes_iterator instead of std::ostream 
Instead of using inefficient std::ostream, use our own 'bytes' iterator class.
Compute ahead of time the length of the byte buffer.
Afterwards serialize the objects into it.

Gives ~X5 boost over previus results (that sometimes don't even
finish in reasonable time)

[avi: add missing include]

6f2a2529a2 add "double" and "float" types 
Implement "double" and "float" cql types.

This implementation doesn't touch serialization.hh (which should be
eventually removed) and rather follows the other examples in types.cc.
It is relatively ugly, because of all the cleverness of our "general"
byte swapping implementation actually works only for integer types, and
we need to get it to work for float/double as well.

99a09020e8 types: Fix bytes_type_impl string conversion 
Tomek points out that:

  Origin calls org.apache.cassandra.utils.Hex#hexToBytes here, which is
  not what to_bytes() does. BytesType.getSerializer().toString() calls
  ByteBufferUtil.bytesToHex(value), so you should call to_hex() here.

Fix that up.

8701273006 Add inet type 
In v2: rebase, and add a more descriptive exception if trying to deserialize
an ipv6 address.

Add to list of types the Internet address type, known as INET in CQL
or as InetAddressType in the Cassandra code.

I based this code on stuff I found in InetAddressType and
InetAddressSerializer in the Cassandra code.
